Abstract
The spatial filtering in an orthogonal frequency division multiplexing radio-over-fibre (OFDM-RoF) network is proposed to boost its capacity using broadband optical true time delay enabled microwave beam steering (OTTD-MBS). The observed suppression ratio of the spatial filtering is 19.4 dB. The optical delivery and directional wireless transmission of 3.975 Gbps OFDM data on a 19-GHz microwave carrier is studied. The observed beam directing induced BER improvement is more than four orders of magnitude.
